C. Because the no x repeats itself in any of the ordered pairs.
It is just asking for you to convert 3/4 in 84ths. This means it wants the denominator to be 84. So multiply both the top and bottom by what gets you 84. In this case, multiply both by 21. So 3/4•(21/21)=63/84
Answer:
Expand the 21(2-x)=42-21x
then you add 12 x with 42-21x
making it 42-9x=44
hence,
-9x= 2
9x= -2
x= - 2/9
hope this helps. :)
